Soft tissue simulator for magnetic resonance testing and method for simulated testing

A soft tissue simulator for magnetic resonance imaging and a method for simulated testing are disclosed. The simulator includes a base for supporting a soft tissue or organ sample, an indenter, a pneumatic cylinder and an air source. The pneumatic cylinder is separated into a first chamber and a second chamber. The air source includes a pneumatic generation source and a reversing valve having a first air outlet and a second air outlet which are respectively connected to the first and second chambers. The reversing valve is used to control compressed air to enter the first or second chamber to control the movement of the indenter. The indenter is controlled to have a periodic or unidirectional movement, to simulate the movement of a human organ or soft tissue. The simulator can used for the measurement of physical characteristics of soft tissue based on magnetic resonance imaging.
